LUBRICATTNG APPLIANCE.

Application fled mm... as, 1924, Serial Io. 752,147, and inl'rano'e gt-(a, 1024 The lubricating ent in motor cargarages, for exam le, comprise a flexible tube containing-t e 'lubricant under hi h pressure. This tube conveys the lubricant directly to the various 7 arts to be lubricated. :In this device, the

. exible tube being" subjected to a high pressure,.is not easily made impermeable and there is a continual risk of its bursting and falling away. from its connections, which involves unfitness for use and considerable loss of lubricant.

Moreover, in these known devices. the o erator is compelled first of all to fit the tu 16 to the part of the motor carto be lubricated, then go back to the oil tank to work the ump and put the lubricant under pressure.

e is compelled to do. all this every time it is necessary to pass from one place to another 0 for lubrlcating.

Finally, during working of the pump the mechanic cannot ascertain whether the lubricant is suitably distributed for lubricanon.

Briefly the known apparatus of large capacity necessitate lengthy operations and do not allow the chaufieur to give continuous attention to his work.

The resent invention relates to a new 80 lubricating device by means of which the receding inconveniences can be avoided. his new device is characterized by the combination of a tank containing the lubricant and a little pump which can be worked by 38 hand, the said tank being connected with the hand pum by means of a flexible tube.

Consequent y the lubricant flows freely under low'pressure from the tank tothe pump through the flexible tube, the said lubricant put under. high pressure by the pump itse f in close vicinitytothe part to be lubricated. The lubricant therefore only runs through the flexible tube undervery low pressure.

Moreover, thechauffeur is near the lib b'ricating mechanism all the time: the ap 'p 'aratus is worklng, so that he can contins ally watchthework of lubrication without I uselessl passing from one place to another,

iierejis some other part to be lubri Gated- I v f I v The invention alsocomprises othercharcombinations.

The lubricant tank'( prises a cylindrical bodly. 5 t e f bottom 6 and a lid 7.in

of t e tank.

atus. comprises two lubricant tank 1 and two-parts being conby a flexible tube 3 6 i and 7) comorm of a hemi spherical cap. This lid" is provided with a groove in its lower edge in-which is placed a packing upper e ring making a tight joint with the go of the cylindrical body 5. -A

flange 70 of similar form. is fitted on this cap' and provided with a. handle 71 and a lateral notch 85.

Bolts 28 28 with nuts 29 29 are interposed between the flange 70, and the base 17 on which the oiltank 56 rests.

extends nearly to the In the tank 1' is a central tube 10 which bottom of the said tank 1, and is connected at its top with a nozzle 72 forming part ,of the lid -7 and intended for the outlet of the lubricant.

A piston slides on the central tube 10 in the tank.

and flanges 16 are provided tacilitating the grip of this piston 1n the mass of lubricant The little pum is 'shown in detail in Figs. 2 and 3, it has t e general form of a pistol, the hollow handle of which receives the end of the flexible tube 3.

The upper part 33 o .passageor screwed f the pum forms a 'the lubricant and is'c osed by a plug 31 into'which the fixed piston 32 of the ump is screwed.-

Thecy inder 35 of the pump can slide freely in anextension 36 of the hollowpump controls the outlet from the pump cylinder 35 and is constantly forced towards its seat by a spiral spring 40.

A spherical tip 41 with a through hole is screwed into theouter end of the pump cylinder 35, and an inverted part spherical cap 78 with exit orifice 79 for the lubricant is fitted on to the spherical tip 41, as is shown in detail in Figs. 4 and 6.

The. working of the apparatus is as follows I The lubricant tank 5 is first put on its 1 stand 17 the flange 70 is turned on the pin 28 so as to be placed over the lid 7. Then the bolt 28 in' the notch 85 of this flange 70 and the two nuts 29}, 29 are screwed down tight on the ends of the bolts 28 28 Thus the lid 7 is tightly held against the plastic packing ring 9 on the edge of the cylindrical tank body 5, and in this way the oil tank is rapidly and tightly shut. I

' Under the action of any available power P such as "compressed air, the piston15 is operated to gradually drive the lubricant through the central tube 10, the nozzle 72 and flexible tube 3. The working of the piston 15 is facilitated by the fact that the said piston grips the mass of lubricant by its flanges 16.

Thus the lubricant is conveyed through.

the flexible tube 3, as shown by thearrow 45 to the hand-pump 2. This said pump is operated to distribute the lubricant to the parts to be lubricated as follows :The

'chaufl'eur grasps the hollow handle 30 of the pump and applies thespherical tip 41, 78 to the circular orifice 46 of the part 47 to be lubricated.

He then pushes in the direction 46 on the pump body which is resting. on the part 47 to be lubricated; the pump cylinder 35 slides into the space 33 of the upper hollow body of the pump, compressing the spiral spring 37. The iston 32 enters the pump cylinder 35 with-but slight friction through the inserted bronze socket 38 and drives the lubricant contained by the pump cylinder 7 35 through the non-return valve 39.

The pumped lubricant runs through the hole channel of the spherical tip 41 and enters the recipient part '47 (Fig. 3).

When the forcing motion of the pump is finished, the chaufleur ceases to exert pressure in the direction 48; the spiral spring 37, compressed in the downward pumping motion and being supported on the inserted plug 31 repels the pump cylinder 35 in the direction 48. This pump cylinder then returns to the cated in Fig. 2 and immediate y fills with a new supply of lubricant. At the same time the nonreturn ball valve 39 is pressed against its seat by the spiral spring 40 and prevents all ingress of air. Thus the hand pump is again ready to pump lubricant.

Briefly, the chauffeur who holds the hollow handle 30 of the pump has merely to exert pressure in the direction 48 on the part for lubrication.

The improved device previously described gives numerous advantages In the first place the lubricant is kept in the flexible tube 3 at a slight pressure, produced by the piston 15; this lubricant is only brought to the requisite high pressure for'use in the pump body 35 in close vicinity to the part 47 to be lubricated. Consequently the flexible tube 3 only works under low pressures and rupture of the tube joints or the tube itself is avoidedf Moreover, handling of the apparatus is very simple. The chaufleur has merely to grasp the handle 30 of this little pistol like pump and exert a pressure on the part 47 tobe lubricated. 1

He can, almost without changing his place pass from one point to another of the mechanism being Lubricated. Finally he can continually follow the "work of lubrication with the eye and regulate it so as to assure a suitable quantity of lubricant being distributed.

It will be seen that the system of closing the lubricant tank 1 is simple and effective, because the lid 7 can be hermeticall closed on the body 5 and the tank fixe on its stand 17. y

Moreover, the said tank can be immediately taken from its stand 17 when empty, for which purpose it suflices to loosen the winged nut 29 and turn the bolt 28 in the direction 86 so as to free the same from the notch 85 of the flange 70. This flange is then turned on the bolt 28 and the lid 7, central tube 10 and the piston 15, are removed.

Another tank 5 filled with lubricant is then placed on the stand 17, the lid 7, central tube 10 and piston 15, being placed in position."

osition indi- Finally it suffices to replace the flange 70- on the hemis herical lid' 7, fix the bolt 28. a in the notch 5 and screw the nut 29 down tight, when the apparatus is again ready for work.

The little hand pump is easily managed and sure in working, in particular the bronze socket 38 being of short length can without great cost be reamed with great against the inner surface of the cylinder- T us the friction produced in working the pump is reduced and any liability o the piston 32 to grip the pump cylinder 35 avoided.

The terminal device represented in detail in Figs. 4 and .5 comprising a double jointing, viz the joint of the part spherical cap 78 on the spherical extremit 41 of the tip for which it forms a spherical seat and the joint of this part spherical cap itself on the recipient art 47.

This evice works as follows The tip of the pistol like pum is pushed onto the recipient part 47 in the irection of the arrow 83, as indicated in Fig, 5, the axis y of the part spherical cap being coincldent with axis :22 av of the tip properly so called.

The combined reactions and frictional forces undergone by the part s herical cap 78 have for effect to make the said part spherical cap 78 turn at a certain angle on the tip 41 in the direction of the arrow 81 so that this cap passes from the osition given in Fig. 5 to that of Fig. 4. he axis 3 y of the cap 78 acquires an'incline B with respect to the axis a: a: of the-lubricating. apparatus, this axis 3/ y itself presenting an incline a in relation to the axis 2 z of the reci ient part 47, consequently the lubricating device can take a total incline of a-l-B in relation to the recipient part 47 passage of the lubricant however remaining assured by the interior conduit 56 and the orifice 79, as shown in Fig. 4.
